Improvement in bracket seats



JOHN J. WILSON, OF NEW YORK, .Y.-

Letters Patent No. 113,607, dated April 11, 1871.

IMPROVEMENT IN BRAGKET SEATS.

The Schedule referred to in these Letters Patent and making part of thesame.

, To all whom it may concern:

Be it known that I, J ons J. WILSON, of the city, county, and State ofNew York, have invented a certain new and useful Improvement in BracketSeats; and the following is hereby declared to be a full and correctdescription of the same.

A folding seat has heretofore been made, in which the seat has been uponthe outer end of a swinging become loose from the constant turning towhich thel bracket is subjected; hence said bracket turns too easilyafter being in use but a short tim'e, and said bracket and seat areliableto be moved by the dress of aperson about to sit upon the seat,which is sometimes the cause of an accidental fall.

ings upon the end of the swinging bracket, and is iitted to moveparallel with the pin upon which the seat turns, and a spring isprovided to keep said seat in its proper position; but it is found thatthe rough usage to which the seat is exposed soon4 causes the V-bearingsto wear, so thatthe seat moves upon its hingepin and becomes veryunsteady in use.

My invention is made with special reference to meeting all thesediicnlties, and `providing a folding seat which will be entirely ,freevfrom all the objections before named.

I make use of journal-boxes for the pivots of the bracket, which areprovided with blocks, forming part of the bearings for said pivots, andfitted so that more or less friction can be applied to said pivots toprevent the bracket turning too easily.

` I also make use of a swinging latch, to set over thel arm of thebracket and keep said bracket in its correct position and `prevent itsturning accidentally.

I make the bearing-surfaces of the lugs which support the turning seatas flat inclined surfaces, which entirely prevents the seat moving4 inits horizontal position; and I 4form the seat itself so that the shapegiven to said seat is from the block of wood forming said seat, and notby the stuffing heretofore usually employed.

4 In the drawing- Figure 1 isan elevation of my improved folding seat;

Figure 2 isa plan of the same; and

Figure 3 is a cross-section at the line a: a', fig. 1.

a represents the bracket of the seat, and

b b are the pivots upon which said bracket swings or turns. Y

c c are the journal-boxes for said pivots, attached to the counter orother vertical surface, c', by the bolts or screws d d, land providedwith the friction bearing-blocks e e.

These blocks e-e are made, as shown more clearly in g. 2, so that theirouter ends will res-t against the surface c', and said blocks should beof such length as to keepv the flangesff of the boxes .c c away from thecounter c', so that more or less friction can be applied to the pivotsby tightening the bolts d d to prevent.

the bracket a turning too freely.

To prevent the bracket and seat moving at all 'when in position for use,I employ the swinging latch h, moving upon the axis i, and provided witha notch at 7c to set over the arm ofthe bracket a, and securely holdsaid bracket when in the position shown in figs. l and 2.

I4 prefer to make the bearings le' for the axis 'L' of the latch withthe L- anges shown, so that more than one screw or bolt may be used tosecure said bearing The seat itself in said patent is supported inV-bearto the counter c', and prevent said bearing. moving from itscorrect position by strain from the bracket a and latch h.

l m fm are lugs upon the outer end of the bracket a, and -n n are' lugsupon the under side of the plate n', which receives the seat o, and'at pp offsets froin the lugs fm m are formed, upon which the under. sides ofthe lugs un rest when the seat is in a horizontal position.

The offsets p p, as well as the under sides of the lugs n ln.,iheingformed with iiat inclined surfaces, as,

shown in figs` l and 3, it will be understood that the tendency oi' thespring tis to force the lugs n n toward the lugs on m and keep thesurfaces. p n in contact, and that such surfaces being fiat, there canbe no play of the seat o upon its axis w.

The body for the seat o is formed of two blocks, e el, the block e beingsecured to'the plate nby screws, or otherwise, and to' the block 'vl Igive the general shaperequired .for the upper part ot' the seat.

Upon the upper surface and sides of the blocks fu two or morethicknesses of wadding are applied, as at o2, to form a cushion for theseat, and over the wadding any vdesired covering may be applied, theends of said covering material extending partially beneath the undersurface of the block e, and secured by tacks, so that, when the twoblocks are placed togeth- Aer as shown in iig. 3, and secured by screwsor otherwise,the ends of said covering material will be out of sight andthere is nothing to mar the appearance of the seat.

I claim asfmy invention- 1. :The swinging latch h, combined with theswing-V ingl bracket al and seat, substantially as and for the purposesset forth.

2. The boxes for the pivots b b of the swinging' bracket and seat, madewith the block e and strap j', the latter being secured by bolts orscrews, so as to apply the necessary friction to the pivots ofV saidbracket, as and for the purposes set forth.

3. The lugs o1, 'n upon the seat o, with nearly flat bearing-surfacescorresponding to the inclined snrfaces p p on the bracket a, incombination with the spring t, as and for the purposes set forth.
